VISE

PATENT FFICE EDWIN W. FULTON, F OSWEGO, NEW YORK VISE The device, thesubject of this invention, is a vise, and the special objects of theinvention are to provide a vise that has not only a plurality ofimprovements, but a plurality of uses.

Up until a short time ago, vises merely consisted of jaws of workholding means, adapted to be closed together, and to hold an objectbetween them. As the faces of the jaws were usually arranged parallel,it was quite obvious that round bodies, such as pipes, cylinders ordisks could not be held between such jaws.

The next improvement was the addition of pipe jaws, as an auxiliary tothe fiat, or machinist jaws, and while such plpe jaws serve to holdpipes or cylinders in one position, still there was something lacking tomake a vise complete and eflicient.

In this invention, I have provided an additional pair of jaws or workholding means designed for the purpose of holding disks or cylinders,and therefore the vise which I have shown, and which I will describe,has three i distinct pairs of jaws, all operated from a single source,and so proportioned that the effect of closing of any pair of jaws willnot be in any way hampered by the premature closing of any other pair ofjaws.

Another object of this invention is to provide means for retaining thescrew or worm which causes the operation of the movable jaw members, andI have included other improvements which will be fully described in thespecification which follows.

The following is what I consider the best means of carrying out myinvention, and the accompanying drawing should be referred to for acomplete understanding of the specification which follows.

- My vise is constructed with a vise member 1 and a plate adapted toswivel thereon. The plate 2 is held in an adjusted position by thecapped bolt 3, which passes through a screw threaded perforation in theplate 2, and enters a recess in the base member 1. The wrench iirremovable from the bolt .3, serves as a means for turning the bolt.

Formed integral with the plate 2, is the body portion of my vise, whichconsists of a cylinder 4, having formed therewith, the stationary jawmember.

The stationary jaw member has an outwardly hooked portion 5 secured towhich is a serrated plate 6, forming one jaw of a machinist vise, and itwill be noted that I 66 provide a recess 7 in the jaw member 6, andallow this jaw member to receive and hold round stock, bars or smallpipe.

Formed integral with the aw member, is a projection 8, in which isreceived the jaw members 9 and 10, which are the stationary members ofthe pipe vise. These members are provided with teeth, as shown at 11,and are spaced apart for a purpose that shall ap pear later. Theprojection 8 has a further outward projection 12, which constitutes aplateor rest, and upon this plate or rest, I arrange a second plate 13having a V-shaped slot 14 therein. This plate is secured by means ofscrews 15 and 16.

.80 A cylindrical member 17 passes through a suitable central portion inthe jaw member and cylinder 4, and in this cylindrical member 17, theoperating screw 18 is enclosed. This screw has an enlarged collar, orcylinder 19, formed integral therewith, and. through which passes theoperating bar 20.

Formed integral with the cylindrical member 17 is the second duplex jawmember. This jaw member has an inwardly hooked portion 21. similar tothe hooked portion 5, and upon this hooked portion 21, the jaw member 22is secured. This jaw member 22 is serrated, and consists of a platewhich is arranged parallel to the member 6, and which co-operates withthe member 6 to complete the jaws of .the machinist vise. A projection24: receives a member 25.

The member 25 is a plate retained in the member 24 by a bolt or setscrew 26. This member constitutes a part of the pipe vise, and istherefore provided with a semi-circular recess in which are arranged theteeth 27. In operation, the plate 25 passes between the plates 9 and 10,so that the diameter of the operating circle may be reduced and/ or sothat this pipe vise may hold pipes of smaller diameter.

The member 24 is also provided with a further projection 28, whichapproaches the projection 12 on the part 8. This projection 28 serves toform a plate, shelf, or support for a disk,and upon the member 28, Iarrange a plate 29, having a V-shaped recess 30, arranged therein, andthis plate 29 may be secured by means of a single screw 31.

At32, in Fig. 4, I show a plate which may be used as a substitute forthe plate 29, and which will make it possible to retain cylinders ordisks of small diameter. The added line 33, in Fig. 2, indicates theposition of a cylinder or disk engaged between thejaws 13 and 29.

From the foregoing description, it will be noted that I have providedthree distinct sets of jaws, each capable of accomplishing a differentuseful work, and yet all co-incidentally operated from a singleoperating means, and under most circumstances, used independ ently.

Upon the cylindrical member 4, I arrange a cap 34, secured by means ofscrews,'oneof which is shown at 35. I have not previously mentioned thatthe cylindrical member 17 has a slot therein, and a tongue not shown,formed integral with the member 34, enters the slot 36 in the member 17,and prevents this member 17 from rotating.

The operating screw 18 passes through the member 17, and projects ashort distance beyond this member, and upon the end of the screw 18, Iarrange a cap 37 having a part 38 thereof, almost, but not quite.completely severed from the capped body 37.

I will refer to this almost severed portion 38, as a plate. The body 37and plate 38 are both screw-threaded upon the operating screw or worm18. and when in such position, the screw 39, which passes through theplate 38 and into the capped body 37, is tightened down, whereupon theplate 38 and a cap 37 will clampingly engage the screw threads 18,

preventing the removal of the cap, and at that the machinist jaws 6 and22 are at one side of the longitudinal center of the screw 18, and thatthe other jaws are arranged directlyopposite, or at the other side ofthe longitudinal center of the screw 18; that is, the jaws are onehundred and eighty degrees apart. This is for the purpose of simplicityof construction and increased strength, and it will be also noted thatthe jaws are so arranged that the presence of a set of jaws in no waylimits the inoperability or efliciency of any other set of jaws.

At 40, I show an anvil plate, which is not new, but which is referred toonly to explain the oblong surface shown in Fig. 2.

It will of course be understood that sizes of all parts may be changedat will; in fact, I do make this vise in all ordinary sizes.

Having carefully and fully described my invention, what I claim anddesire to secure by Letters Patent is 2- In a vise, a plurality ofprojections adapted to approach each other, and a plate upon each saidprojection, each said plate being provided with a V-shaped slot therein,said plates being arranged fiat upon said projections and a portion ofeach projection extending beyond its associated plate, to preventpassage through said V-shaped slots.

the same time, preventing the screw 18 from I being withdrawn from thecylindrical member 17.

It will of course be understood that as in ordinary vises, the screw18is screw threaded through the body cylinder 4, and it will be observedthat when the vise is fully opened, the cap 37 will engage theprojection from the member 34. which enters the slot 36, limiting theopening of the jaws, and preventing.

them being separated.
